Nondual awareness (NDA) is a unified, unchanging state of consciousness without other mental contents, often achieved through contemplative practices and linked to well-being. This study validated a French version of the Nondual Awareness Dimensional Assessment-Trait (NADA-T) scale, which measures predisposition to NDA during mindfulness meditation or experiences with reduced mental activity. Among 294 French-speaking students who completed an online survey, the original scale structure—one global factor (NDA) and two specific factors (self-transcendence and bliss)—showed very good statistical indicators. Convergent and discriminant validity were also good. Recommendations included reformulating two items. The preliminary French version shows acceptable psychometric properties in a student population, but further studies are needed to confirm factor structure, test temporal stability, and extend results to other populations.
